These doors necessary to adapt it to use in the present 2 are mounted on the vehicle body with their structure free edges in opposed relation and having the A still further object of the invention is to stile post 2 therebetween, in the manner usual 7 provide a novel means for actuating a pluin the majority of motor vehicles at present rality of bolt elements from one point and in use.

Suitable spacing elements 8 are interally a transverse section through thet-wo sides p sed between the upper and lower edges of of the body frame of a motor vehicle illusthe plate 6 and the inner face of the door to trating the manner in which the locks upon which the lock is attached and securing elethe two sides thereof are controlled from ments 9 are passed thro gh h se pacing elene point, this section being taken across the ments and the plate 6 to engage in the body vehicle body substantially upon the line 1v-l of the door. 1 r r of Figure 2; The bolt 4: of each door lock rides upon Figure 2 is a view looking at the inside of supporting or carryingpins 10 which extend one side of the body frame showing the disacross between the side plates 6v and 7 ofthe position of two door locks, one of which is in, lock, these pins passing, through a suitable section, and the means forming a part of the longitudinal slot 11 in the bolt and on a i 50 present invention for securing them against suitable supporting pin 12 carried by the side v the squared inner end 16 of a door handle 17 This sleeve has formed integral therewith a stop lug 18 and a bolt actuating finger 19. The finger 19 is normally vertically disposed between the face plate 5 of the lock and a I In 20 which is carried by the bolt 4.

eneath the sleeve 15 in each lock there is oscillatably mounted upon the pin 21 which extends transversely between the plates 6 and 7, a latching finger 22 which when oscillated upwardly upon the pin 21 comes into position before the face of the stop lug 18 and oper-- ates to prevent the rotation of the sleeve 15. This latch finger 22 has an extension 23 with which is engaged a spring 24 carried between the plates, which normally depresses the latch to prevent it interfering with the oscillation of the sleeve.

The latch finger 22 has formed integral therewith adjacent its pivoted end and depending beneath the pivot pin, a contact plate 25 which normally positions against the face plate 5 and overlies an aperture 26 in this plate. These apertures 26 of two adjacent locks are aligned transversely of the stile post 1 disposed therebetween.

Upon one side of the vehicle body upon the stile post is secured a unit 27 comprising inner and outer spaced parallelplates 28 and 29 separated by interposed longitudinally extending bars 30. One of these plates as for example, the plate 28 has a longitudinal rib 31 extending longitudinally of its inner face, which rib engages in a suitable groove 32 extending longitudinally of one face of a downwardly pointing wedge member 33. This wedge member is disposed to slide longitudinally of and between the plates 28 and 29 and has the downwardly converging cam faces 34, each of which engages one end of a reciprocable pin 35 which is mounted in a bar 30 to shift transversely thereof. These pins 35 are in alignment transversely of the unit 27 and are also aligned with the apertures 26 in the adjacent lock face plates. Spring elements 36 engage the pins 35 and normally tend to draw them inwardly when the wedge 33 is shifted toward the upper end of the unit of which it forms a part.

At the opposite side of the vehicle body from the unit 27 there is mounted a unit similar to the unit 27 which is indicated as a whole by the numeral 37.

This unit 37 also has a wedge member which is indicated by the numeral 38 and which is mounted upon the inner plate 39 thereof to slide upon the v longitudinal rib 40. This wedge member 38 has the converging cam faces 41 directed upwardly instead of downwardly as the wedge 33, this wedge 38 is an open frame 42 which is at the bottom thereof.

Mounted in the stile post 1 adjacent the unit 37, is a lock 43 which is key-operated and which is of the type which has a central shaft 44 which is rotated by the operating key. This shaft 44 of the lock 43 extends through the stile post and into the frame 42 and upon its inner end it carries a cam finger 45 which is housed in the frame 42 as illustrated in Figure 5. It will thus be seen that upon actuation of the lock 43 the cam finger 45 may be oscillated against one wall of the frame so as to shift the wedge member 38 longitudinally of the unit 37. This wedge member 38 has each of its cam surfaces 42in contact with one end of a reciprocable pin 46 and the two pins of this unit are'aligned as shown and like the pins 35 are normally drawn inwardly by the springs 47. These pins, as will, of course, be understood, operate to actuate contact plates 25 of locks adjacent thereto.

Extending across the vehicle body from the unit 27 to the unit 37 is a tube 48 in which is a flexible wire 49. At one side of the vehicle body this wire is connected to the downwardly directed point of the wedge 33, while at the other .side it is connected with the frame 42, as shown inFigure 5. This tube is set in a suitable groove or recess 50 in the stile post so as to be flush with or beneath the inner faces thereof the same as the locks and the units 27 and 37 respectively.

From the foregoing it will be readily apparent that upon the actuation of the lock cam finger 45 the wedge '38 will be forced upwardly to project the pins 46 outwardly against contact plates 25 of the adjacent door locks and through the medium of the wire 49 the wedge 33 of the locking unit 27 will be drawn downwardly and will thus project the pins 35 outwardly against the contact plates of the locks between which this unit is mounted. It will thus be seen that by the manipulation of one locking key all four of the vehicle body door locks will be secured so that the bolts thereof cannot be reciprocated for each of the latching fingers thereof will be shifted into the position where it will abut the face of the stop lug 18 adjacent thereto and thus the associate sleeve 15 cannot be oscillated to shift the lock bolt.

While the present description has been confined to a motor vehicle body it will, of course,

be apparent that this locking mechanism may be used in other capacities and it may also be employed for locking remotely positioned or related single doors as well as remotely related pairs of doors.
